"You can break everything down to chemicals, but you can't explain a love like ours."

Hey Everybody,

So recently I have found a song called, "Science and Faith" written by "The Script" on Youtube, and what I found intriguing about the video were the lyrics themselves. My interpretations of the lyrics were that there cannot be an explanation of love through science alone, even though there are biochemical basis for the science of  love through various neurotransmitters such as dopamine, norepinephrine, and serotonin. In other words, I think that there is a greater explanation of "real" love, as oppose to lust, in which the human mind cannot fathom. Thus, in my opinion, there is a greater meaning behind the concept of love because if love is just about chemicals between two individuals reacting simultaneously then the concept of love to me would be diminished to just pure chemistry and the probability of such a reaction to occur. Love has a greater meaning to me because if it just about chemicals being triggered by certain physical stimuli then how can one explain love with an individual who is an identical twin? Physically, they look the same so theoretically through the explanation of science and neurotransmitters, should that individual have the same warm, fuzzy feelings for the other identical twin as well? In other words, what would cause the release of certain neurotransmitters for one individual, but not the other? It obviously cannot be something physical in the case of "real" love with an identical twin, so what could it be? To answer this question, I think that one should take a step towards faith because the connection between faith and science is that science is the reasoning behind things, such as love, whereas faith is the belief system behind the reasoning. In the case of love, you have to take a leap of faith and believe that what you are feeling could be "real" love because drawing upon the past, all great scientists, such as Watson and Crick (The structure of DNA), took great leaps of faith in order to believe what they are trying to prove was actually there or is true.
